General Description
The AT1731 is a PWM DC/DC converter control IC with 2 channel outputs that can directly drive power MOSFET.
This IC ia suitable for very small DC/DC converters because of their small and thin package(1.1 mm max.), and high operation frequency (up to 1.0 MHz).
Key Features
- Low input voltage: 2.5V to 7V.
- 2-Channels PWM Control: 1 Boost Controller(CH1) 1 Inverting Controller (CH2).
- Adjustable Soft start time and maximum duty cycle.
- Built-in timer latch for short circuit protection: Delay time=216/(Switching frequency).
- Built-in under-voltage lockout, thermal shutdown.
- High operating frequency: 100kHz to 1MHz.
